Patent CA-2130540-A1 (CA)
Title: Optical Fiber Package
Inventor: MACDONALD WILLIAM M
IPC: G02B6/02
Filed: 1994-08-19
Abstract: A package that protects an optical fiber from strain or controls the strain to which the fiber is subjected for a desired effect and a method for making thepackage are disclosed. The package is a sleeve with an internal passage in which a portion of an optical fiber is placed. The optical fiber and the sleeve are made of materials with coefficients of thermal expansion that are the same or different.If the coefficients of thermal expansion are the same, the package protects the fiber from certain strains brought about by a change in temperature that would otherwise result if the package and the fiber were made of different materials. However, by selectively mismatching the coefficients of thermal expansion of thepackage and the fiber, a change in temperature can be used to bring about a desired change in the wavelength of a grating written in the fiber. The optical fiber is fixed in the sleeve by epoxy or other adhesive means at least at one point in the internal passage of the sleeve.

Title: Ground fault circuit interrupter with immunity to wide band noise
Inventor: MACKENZIE RAYMOND W
IPC: H01H83/02
Filed: 1994-09-15
Abstract: In a ground fault circuit interrupter in which it was found that wide band noise induced by load transients is rectified by an op-amp In the detector circuit, false trips due to the wide band noise are eliminated by only comparing the output of the amplifier with a threshold of opposite polarity to that of the rectified noise signal and by eliminating capacitive coupling between the current sensor and the op amp. This requires an op amp with a low offset, on the order of about five percent or less.

Title: A seed coat-specific cryptic promoter in tobacco
Inventor: MIKI BRIAN
IPC: C12N15/82
Filed: 1995-05-09
Abstract: T-DNA tagging with a promoterless .beta.-glucuronidase (GUS) gene generated a transgenic Nicotiana tabacum plant that expressed GUS activity only in developing seed coats. Cloning and deletion analysis of the GUS fusion revealed that the promoter responsible for seed coat specificity was located in the plant DNA proximal to the GUS gene.      Analysis of the region demonstrated that the seed coat-specificity of GUS expression in this transgenic plant resulted from T DNA insertion next to a cryptic promoter. This promotor is useful in controlling the expression of genes to the developing seed coat in plant seeds.

Title: Turbomachinery having variable angle flow guiding device
Inventor: HARADA HIDEOMI
IPC: F04D29/46
Filed: 1995-12-28
Abstract: A turbomachinery having variable angle diffuser vanes is demonstrated with the use of a centrifugal pump.   The performance of a diffuser is enhanced greatly by the use of adjustable angle diffuser vanes which can be set to a wide range of vane angles to provide a variable size of an opening between adjacent vanes.  The demonstrated pumping system has a significantly wider operating range than that in conventional pumping systems over a wide flow rate,  and is particularly effective in the low flow rate range in which known diffuser vane arrangements would lead to surge in the entire system and other serious operational problems.   A number of concrete examples  and  formulae  are  given  to  demonstrate  the computational methods used to select a vane angle for a given set of operating conditions of the turbomachinery.
